| Abstract: | In this thesis, we determine the dispersion managed (DM) soliton solutions in an optical fiber communication system using the split-step Fourier method and a numerical averaging technique. A dispersion managed system is one in which the dispersion varies periodically along the fiber, in a conventional system, the dispersion is constant. Analytical solution exists for conventional soliton systems but not for DM soliton sytems. We compare the properties of the numerically obtained DM soliton solutions with that of the conventional solitons. Split-Step Fourier Method, although very simple to implement, has its drawbacks. We implement a finite difference method to solve for the DM solitons and compare the performance of the finite difference method to that of the split-step Fourier method. We find that the finite difference method is more efficient than the split-step Fourier method. |
